Quote: I tried one too, will give it a test run tonight. Scaled the drawing (Thanks Snowdragon!), printed, glued it to a piece of cardboard from the back of a pad of notebook paper, cut a plastic container lid that is a close fit, done. Cost $0. If I like it, I plan to buy John's... Jim
Hey Jim, let me know how that refractor style mask works out! I am really excited to see if it works better for a refractor than the SCT design.
